Relevance of Nanotechnology in Solving Oral Drug Delivery Challenges: A Perspective Review.

Nanotechnology is opening up new opportunities in drug delivery, including oral delivery, and it may reduce toxicity and increase drug ability. Presently, researchers are expanding their knowledge in the development of oral nanomedicine to extend the scope of oral drug delivery and exhibit excellent platforms for drug transportation, target, and controlled release. The present review is an attempt to define updated oral nanostructured systems for the delivery of a wide range of drugs. The review also focuses on the use of different polymeric and other materials, technologies adopted, and benefits/drawbacks of delivery systems.
